Electronic cigarettes have had a surge of popularity in recent years, with many people turning to them as a healthier alternative to a traditional cigarette, or as a stepping-stone to quitting altogether. With e-cigarettes, smokers inhale a vapor the device creates from a nicotine-laced liquid solution, and consumers often believe e-cigarettes to have lower levels of nicotine and carcinogens than the traditional alternative.
But a new study from the National Consumer Institute in France showed that e-cigarettes are likely to be at least as harmful to a person's health and can still cause cancer. In fact, they may be even more harmful because of unknown chemicals which are added to the nicotine solution. A report released in July by the World Health Organization and reported by the Examiner said "the products vary widely in the amount of nicotine and other chemicals they deliver and there is no way for consumers to find out what is actually delivered by the product they have purchased." Because of the health risks, the Food and Drug Administration wants e-cigarettes labeled like the nicotine patch or nicotine gum. [Source][Source]
